US Nitrogen LLC has been given another 30 days to collect data requested by the state to back up the company's own request for a loosening of opacity limits during startups and shutdowns of its nitric acid plant.
In a letter this week to USN's plant manager Dylan Charles, Michelle Owenby of the Tennessee Department of Environment and Conservation wrote that at the company's request the new deadline to submit the data has been set for April 19.
Opacity limits have been an issue since US Nitrogen opened its Greene County manufacturing facility in 2019.
According to Owenby's letter the extension was not formally requested but was sent to a TDEC official in a Feb. 21 email from Steven Wallace, a USN environmental official.
The extension is just the latest in a series of back-and-forth exchanges between the chemical firm and state environmental on the limits on opacity limits duirng the startups and shutdowns at the acid plant. The nitric acid is used in the production of ammonium nitrate, USN's principal product.
Though the state had been developing those opacity standards, USN asked for a delay, but then reversed itself and asked the state to resume its efforts.
TDEC then asked USN for the additional data and gave a 30 day deadline for submission. That triggered USN's request for the 30 day extension.
